At 1:30 or so of this clip, what looks like footage from The Beatles: Rock Band goes up on the screen behind Sir Paul McCartney, performing at Coachella on Friday.

The clip is 9 minutes long, but of the ones circulating out there, it offers the longest and clearest look at Rock Band's animations. Which it has to be, the face texturing and the cuts have that RB feel.

it was a night of firsts and was the unexpected, unannounced world premiere of the images from the coming Beatle Rock Band game

Destructoid was tipped to another clip here, which is shorter, but is of the same set - "Got to Get You Into My Life." Tons (sigh tonnes) of people have camcorders up in the air filming the screen, making this, what, a GDC presentation or something?
